POWER-TRANSNI ITTER.

SPECIFICATION forming part of Letters Patent No. 662,179, dated November 20, 1900.

Application iled February 27, 1900. Serial No. 61738. m mOdGL) T0 cir/ZZ whom t may concern:

Be it known that I, FRANK S. WEATHERLY, a citizen of the United States, with residence and post-office address at 228 East Second street, Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Power-Transmitters, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to a power-transmitter such as shown in my application Serial No. 724,128, in which reciprocating motion is changed to rotary motion, also means for reversing the rotary motion and means for dispensing with any shock or sudden start in changing from the reciprocating motion to the rotary motion; and my invention consists in certain features of novelty hereinafter described and claimed.

Figure I is a side elevation of my improved device. Fig. II is a top view. Fig. III is an end view. Fig. IV is a detail view showing method of reversing. Fig. V is a longitudinal section taken on line V V, Fig. II. Fig. VI is a side elevation of one of the segmental gear-wheels. Fig. VII is an edge view of one of thesegmental gear-Wheels. Fig. VIII is an edge view of one of the segmental gear- Wheels, showing reversing device. Fig. IX is a side elevation of my improved device, showing the side of the bed-plate removed. Fig. X is an edge View of the reversing gearwheel. Fig. XI is a side elevation of the reversing gear-wheel. Fig. XII is a plan view of the clevis for connecting the reversing yoke with the segmental gear-Wheel. Fig. XIII is a detail side elevation of the segmental gear-wheel.

Referring to the drawings, 1 represents a bed-plate of any approved construction, having a base 2, vertical sides 3, and ends 4.

represents upper and lower guide-plates extending the full length of the bed-plate, resting upon the upper edges of the sides 3 and secured thereto by means of bolts 6, said bolts preferablyextending through the base of the bed-plate and through the sides 3. The guideplates 5 are placed a short distance apart, leaving a horizontal Working space 7.

3 9 represent my double reciprocating power-rack, having teeth ll, which engage the segmental gear-wheels 13 14. The racks 8 9 are placed some distance apart and secured at 15 to cross-heads 16. The cross-heads 16 extend across the bed-plate, with their ends resting in the horizontal space 7 between the upper and lower guide-plates 5.

17 represents a piston-rod connected with one of the crossheads 16, by which reciprocating motion is imparted to the racks 8 9. The racks 8 9 are placed some distance apart both horizontally and vertically with the teeth of one rack presented upwardlyand those of the other rack presented downwardly. The racks are provided with legs 1S, which are bolted to cross-heads 16, said racks being strengthened by means of braces 19, connecting the racks at 20 with L-shaped projections 2l, said projections being a right-angle consecured to the cross-heads 16. The segmental gear-wheels 13 14 are loosely mounted upon a sleeve 22, the sleeve being in turn loosely mounted upon a power shaft 22, each of said segmental gear-wheels engaging the teeth of its respective rack, so that as the racks are reciprocated in the bed-plate .the segmental gear-wheels will partially rotate upon the sleeve 22 in opposite directions.

23 24 represent ratchet-wheels iixed to the sleeve 22 on the outside of the segmental gearwheels 13 14.

25 represents spring-pawls adapted to engage Vthe teeth of the ratchet-wheels 23 24, said' pawls being pivoted to pins 26, extending out from the sides of the segmental gearwheels 13 14, said pawls being so placed on the said segmental gear-wheels as to engage the teeth on either side of the ratchet-wheels 23 24, according to circumstances.

27 represents yokes which straddle the nontoothed part 28 of the segmental gear-wheels.

29 represents spring-rods extending from the pawls 25 to the yokes 27, the ends of said spring-rods 29 passing through staples 30 on said yokes, the result being that as the yokes 27 are shifted upon the segmental gear-wheel (see dotted line, Fig. VI) the respective pawls 25 will either be thrown into contact or out of contact with the ratchet-Wheels 23 24.

3l represents a clevis connected with the yoke 27, said clevis having a bolt 32, which IOO extends through the yoke 27. The yoke is held in the position to which lit is thrown by means of the bolt 32, passing into notches 33 in the segmental gear-wheels 13 14, said yoke being rmly pressed down upon the segmental gear-wheels by means of a curved spring 34, having one end fixed at 35`to the segmental gear-wheels and its opposite end curved over shoulders 36 on the yokes 27, the clevis 31 also extending over the free end of the spring 34, thus holding it in position.

37 represents areversing gearlwheel loosely mounted on the sleeve 22 between the segmental gear-wheels 13 14. The wheel 37 meshes with a segmental rack 38', whichn is pivoted at 39 to the bed-plate.

40 represents a compound lever for operating the rack 38.

41 represents lugs on each side of Athe reversing gear-wheel 37, the outer ends of said lugs as the reversing gear-wheel 37 is rotated engaging within a semicircular recess 42 on the inner face of the yokes 27, so that a single revolution of the reversing gear-wheel 37 by the manipulation of the lever 40 and the segmental rack 38 will cause the lugs 41 to `enter the recess 42 in the yoke 27 and by pressure change its position. (See Fig. IV.) As the position of the yoke is changed the pawls 25 are changed and the sleeve 22 is compelled to travel in the opposite direction.

43 represents a bar for confining and guiding the lever 40.

44 represents coil-springs coiled upon the power-shaft 22, having their inner ends secured at 45 to the'sleeve 22 and their outer ends secured at 46 to the power-shaft 22. The object of the springs 44 is to prevent the otherwise unavoidable jerk or jolt on each stroke of reciprocating movement, converting the latter into a rotary motion smoothly and without shock. The springs contracting and expanding act as a storehouse, giving and delivering power, receiving it intermittently, and delivering it steadily, as in watches, clocks, &c.
